Remembering how much Boner dominated that fight when you had full drive, I'd tend to agree. However I feel that for this particular size and shape of robot, the wedge will be beneficial. Though it may not be as effective as having the teeth scraping the floor, the added strength that's now there offers a bit more protection against horizontals, which is something I've wanted to do for a while.

There's also not a huge amount of space between the wedge and the drum teeth so even if a robot rides up it just a little, chances are I'll skelp their underside. Plus the extra resistance of the wedge running on the floor helps tame any erratic movements in the drive, which should help towards improving driving precision.
